As a long time DBA and Database Architect this idea is
repugnant – make a database 100% de-normalized; one table and
except for the one query, retrieval by primary key, nothing else
works. And yet we have had great success using this kind of
database.

This does not replace the original normalized database, rather it
is more like a permeant cache fed from the main database.
It is a MySQL
database which has certain advantages over Memcached or
other true caches such as it is permanent until our processes
replace it.
